Aurora vs Solargraf: The NEM 3.0 Storage Teardown
The Problem: California's NEM 3.0 fundamentally changed the ROI math for solar by shifting value from export credits to self-consumption. Installers now face a critical bottleneck: sizing batteries accurately against the new Avoided Cost Calculator (ACC) to prove long-term ROI to skeptical homeowners. Standard monthly averaging models are no longer sufficient; granular, hourly dispatch logic is required.
For strict NEM 3.0 compliance and storage upselling, Aurora’s native modeling engine provides the highest fidelity ROI projections. Their capability to simulate hourly battery dispatch against the ACC prevents overpromising savings, protecting your margin from post-install clawbacks and customer disputes.

Lumen's Take
When selling under NEM 3.0, the tool you use to calculate the Avoided Cost is as important as the hardware you install. Solargraf is making strides, but Aurora's deep integration of hourly dispatch modeling creates a protective moat around your sales claims. You pay a premium for Aurora, but the reduction in canceled contracts due to 'unbelievable' ROI numbers often covers the software cost.
